CONVERTIBLE WINDOW-SASH.

Application fil ed May 15, 1919. Serial No. 297,334.

mounted to swing upon horizontal pivots as well as to be moved upwardly and downwardly on the window-casing in the usual manner.

In window-sashes of this type which have heretofore been constructed, the sash has been insecurely mounted upon the sliding stiles to which it was pivoted, resulting in danger to the person manipulating the window and also in danger of breaking the glass due to the'faot that the sash was liable to become disconnected from the slid ing stiles upon which it was pivotally mounted.

The object of this invention is to securely mount the sash upon a pair of sliding stiles so thatit may be tilted at diflerent angles and firmly locked in position at any desired angle.

One of the advantages of my invention is that not only may new window-sashes be constructed in accordance with it, but old window-sashes already constructed, or in place, may be easily fitted with parts so thatthe same will then be constructed in accordance with the principles of my invention.

Eachof the stiles 11 is formed of two sepa- A rate parts, the outer stile12 and the inner stile-13. The inner stile13 is rigidly fixed to the upper and lower cross pieces l t and 15;

of the sash and toit is attached the-window glass 16. "The outer stile 12 is designed to slide upwardly and downwardly in the usual manner in the window frame 17 stile 12 is pivotally connected to the inner stile 13 by the horizontal pivot 18, seen most clearly in Figs. '1, 3 and 4 and comprising a H pin portion 20, an enlarged portion 21 and tween said pin portion and said enlarged portion. The pivot 18 is firmly fixed in any proper manner at the outer extremity of i the enlarged portion 21 to a reinforcing 24; which runs the entire length thereof, the

opening of which istoward the inner face thereof. The walls of the slot 24 are preferably lined for at least a portion of their length with metal. The inner stile 13 is'provided with a slot 25. This slot ispreferably formed in a metal member'26 and the opening of the .slot is looatedexactly opposite to the opening of the slot 24: when the outer. stile 12 and the inner stile 13 are in'their normal or closed positions. The metal part.

26, which is located entirely within the inner stile 13, has an enlarged portion 27 which The outer The enlarged portion 21 pro- Said recess is en -a hemispherical shaped flange 22 located be a v projects toward the' inner side of the inner stile 13. The recesses adapted to receive the pin portion 2Q and the flange 22 of the piVO j 18 are preferably located in the ienlar ed portion 27 of the metal member 26. he enlarged portion 27 is also provided with a cylindrical aperture 28 passing from its outer surface and at right angles to the pin portion 20 of the pivot 18 and intersecting said pin portion in the manner hereinafter described. The aperture 28 is adapted to receive a screw 29; which is threaded at one end and provided-with a head 30 to enable the same to be turned. The top of the head 30 is preferably flush with the surface of the inner stile 13 located on the inside of the room.- The lower end of the screw 29 is smooth and tapereddownwardly and this portion 31 is adapted to engage a peripheral groove 32 in the pin'portion 20.

Slidable' Within the slots 24 and is a locking slide 33 preferably made of metal. The locking slide 33 is provided with'two 7 slots 34 shaped as shown in the drawing,

, may be grasped. When it is desired to re- 'volve the window-sash on the pivot 18 the r'ag rasps the head 36, lifts the look ing slide 33 so far as the pins-35'i'vill per- 7 ni-it, and said locking slide 33 traveling the path prescribed by said pins 35 and slots 34 moves upwardly and inwardly and is lightly held in its uppennost position by the pins 35 due to the shape of the lower portion of the slots 34. Then in said uppermost position the locking slide 3-3 is ntirely Within the slot 25 of the inner stile 13', and said inner stile 13 with the portions of the window-sash thereto attached is free to revolve upon the pivot 18. When ithas been so revolved to any desired position it is locked in said position by turning the locking screws 29 so that the tapered portion 31 impinges tightly against the walls of the peripheral groove 32 of the pin portion 20 of the pivot 18: When the window is so locked in a revolved position and it is de sired to again place the sashes in the normal or clesed position the locking screw 29 is unscrewed so'tha't-thef tapered portion 31 shall be. disengaged from the walls ofthe peripheral groove 32.

, then hemm d back to its normal position and the locking slide 33 dropped by the operator grasping the head 36 and lowering tages of a direct draft.

The window can'- theilocking slide to its lowermost position. It will be borne in mind that in the foregoing description reference has been made to one stile only. Ever window has a pair of stiles. The construction and operation of the parts of the remaining stileis exactly the same as those of the one stile described. Ifthe outside of the window frame is rovided with fixed bars the pivot'18 shoi'il'd e located near-the bottom of the window sash instead of near the center thereof in order that the windmv may swung in wardly in spite of theoutside bars. When so desired the 'window'may be revolved on its pivots to allow ventilation. This will enable a person to sit in front of the window and secure fresh air without the disadvan- Vhen the window is tipped for the purposes of ventilation it may bedesirable to place a weather strip of the necessary thickness on the windowsill in suchposition that when tipped the lower cross piece of the iwindow-sash will be snug against said weather strip. At

' this point I wish to call particular attention to the pivot 18' and the advantages which accrue from my construction. As before stated, the p'ivot has been the weak point in all previous convertible windows." Priorto 1 my invention the pivot has consisted of a simple pin projecting into opposed recesses in the outer and inner stiles. In nearly all windows and more especially in broad win dows, if the window was lifted, as was often the case, by lifting on only one side thereof, such side tended to lift faster than the opposite' side and the pivot on said opposite side having but slight hold in its recesses as must necessarily be'the case, became disengaged. This was noticeably so when said recesses had become enlarged through use. This caused the two stiles at that point to separate and when so separated the stiles on the opposing side of the window-sash separate'd, the pivot fell out, the parts of the window became separated and the person operating the window was placed in danger. This weakness of the pivotal connection also caused the v'vindow to be rattled by the wind and was of generally weak and poor con-j structiom The construction of my pivot 18 does away with all of the weaknesses, disadvantages and objections above mentioned. The outer end of the pivot 18 being fast to long reinforcing strip 19, which in turn is firmly fixed to ,the outer edge of the outer stile 12 throughout its entire length,-if so desired," makes it absolutely impossible for the pivot 18 to become separated from the outer stile 12.- Neither can the pivot 18 become separated from the inner stile 13* because of the fact that the locking screw 29, whether it is bearing directly against the walls of the peripheral groove 32 or not; is so constructed and located that the pin por tion 20 of the pivot 18 cannot be withdrawn from the recess in the inner stile 13 any farther than the walls of said peripheral groove 32 will permit. The flange 22 also tends to make the pivotal connection rigid and tight in that it prevents any lateral play between the outer and inner stiles. Attention is also drawn to the fact that the pin portion 20 might be broken from the pivot and yetthe outer and inner stiles would be properly to said strip and projecting into the other 'of said stile portions transversely thereof,

and a locking screw on said inner stile portion adapted to engage the walls of a circumferential groove provided on said pivot.

2. A window-sash, having two oppositely disposed stiles, each stile being divided longitudinally thereof into an inner and an outer stile portion, a reinforcing strip fast to the outer edge of said outer stile portion,

a pivot fast to said strip projecting through said outer stile portion and into said inner stile portion transversely thereof, and a flange on said pivot located in a recess provided in the edge of said inner stile portion adjacent to said outer stile portion, whereby said sash is pivotally mounted on said outer stile portions.

3. A window-sash, having two op ositely disposed stiles, each stile being divided longitudinally thereof into an inner and an outer stile portion, a reinforcing strip fast to the outer edge of said outer stile portion,

a pivot fast to said strip projecting through said outer stile portion and into said inner stile portion transversely thereof, and a flange on said pivotlocated in a recess provided in the edge of said inner stile portion adjacent to said outer stile portion, whereby said sash is pivotally mounted on said outer stile portions, and a locking screw having a screw-threaded engagement with said inner stile portion and a tapered end ada ted to' project into and engage the walls 0 a circumferential groove provided in the periphcry of said pivot.

l. A window-sash, having two oppositely disposed stiles, each stile being divided longitudinally thereof into an inner and an outer stile portion, a reinforcing strip fast to the outer edge of said outer stile portion,

a pivot fast to said strip projecting through said outer stile portion and into said inner stile portion transversely thereof, and a hemispherical shaped flange on said pivot located in a recess provided in the edge of said inner stile portion adjacent to said outer stile portion, whereby said sash is pivotally mounted 011 said outer stile portions.

In testimony whereof I have hereunto set my hand in presence oftwo subscribing witnesses.
